RE: <Rambus is not trying to change its 'formula' (design).> Not unless David Lammers report from IDF correct. eetimes.com Below is a part that I extracted quoting Geoff Tate. If they actually change the on-chip banks it will be a huge change which requires that all memory designs and all controller designs be changed and old chips and new chips become incompatible and cannot be mixed. ---------- From Lammers article ------------------- Geoff Tate, chief executive officer of Rambus, said that over the past few years, Rambus and the RDRAM vendors have come to realize that having so many on-chip memory banks made it more difficult to efficiently lay out the redundancy bits needed to keep yields at respectable levels. Adding redundancy bits for each bank added to the chip's die size, and thus increased costs. Cutting redundancy bits can also raise costs by reducing yields. "If we knew then what we know now about the die size impact, we would have decided on fewer banks. But the issue is not just reducing the number of banks, it is making sure there is compatibility among the various DRAM vendors," Tate said. Tate said he expects the memory-bank issue to be decided in the next few months. As vendors create new mask sets for shrink versions of the various 128-Mbit RDRAM implementations, the reduced-bank design would be implemented.
